Application September 27, 1947, Serial No. 776,494

The present invention relates to a mounting for telescopes of the typeused in connection with small arms such as rifles.

It is customary in marksmanship practice to mount a telescope on thebarrel of a rifle to increase the range of vision with respect to thetarget, and to provide such mounting with suitable adjustments to takecare of windage and corrections in elevation according to the range.

It is an object of the present invention to provide an adjustable mountfor a telescope which is compact in construction and renders lateral andvertical adjustments of the telescope precise and easily made.

Other objects of the invention will be apparent from the followingdescription and accompanying drawings.

In the drawings,

Figure 1 is a view in section of a telescope mount constructed inaccordance with the invention;

Fig. 2 is a view in lateral elevation of the mount shown in Fig. 1; and

Fig. 3 is an exploded view partly in section of the assembly shown inFig. 1.

Referring to the drawings, the body I of the telescope mount is providedwith a large central aperture through which the body Ia of a telescopelprojects. The body I is provided with an upper aperture 2, as shown moreclearly in Fig. 3, and

30 position shown in Fig. 1 and the outer telescoping a lateral aperture3; the apertures 2 and 3 having their axes disposed at right angles, andboth apertures having countersunk portions on the interior of the body Ifor accommodating the parts of the adjusting devices.

Referring further to Fig. 3, a threaded section of a rod or bolt 4 isadapted to receive an interiorly threaded and knurled adjusting nut 5,'and the two parts, when assembled, are inserted through the aperture 2from within the body I so that the nut 5 rests within the countersunkportion of the recess and the end of the rod 4' projects through theaperture 2 for receiving a locking nut 6. By reference to Fig. 2, itwill be noted that the edge of the adjusting knob 5 projects beyond thebody I and may be manipulated manually. Similarly, the lateral aperture3 is provided with a threaded rod 9 which cooperatesv with a knurledadjusting nut Il) and is secured in position by a locking nut I I.

When the parts thus far described are in position in the body of themount, a spring 'I is inserted in a recess in the mount, and its freeends extend respectively into longitudinal slots cutin the bars 4 and 9.The spring is maintained in the recess by a pin 8. By this means aresilient bias is applied against the inner faces of the adjusting nuts5 and I0 to retain the assembly in operative position before theclamping or locking nuts 6 and II are tightened. That is, when the partsare assembled as in Fig. 1, the adjusting nuts may 6 Claims. (Cl. 33-50)2 be rotated respectively to change the positiony of the telescope bodyboth vertically and horizon; tally. To facilitate such adjustment, thefaces of the nuts 5 and I0 are provided with serrations which bearagainst the arms of the spring I s that upon rotation of such nuts, asequence ofI clicks will be produced to give the marksman an indicationof the proper degree of adjustment for the range and windageencountered. After l0 such adjustment, the nuts 6 and II may be screweddown to maintain such adjustment'.

It should be noted that the spring 'I serves a number of purposes.First, it maintains the rods 4 and 9 and their respective adjusting nuts5 and IU, in operative position until the clamping nuts eration of thenuts 5 and I0.

The body I is also provided with an aperture I2, the axis of whichextends on a line intersect; ing the axes of the apertures 2 and 3. Adevice for providing a spring bias against the telescope 2'5 body, andthe movement thereof imparted by adjusting nuts 5 and I0, comprises apair of telescoping cup members I3 and I4 which house a resilient membersuch as a coiled compressed spring I3a. The assembled device is insertedinto the member i4 is secured in position with respect to the .body ofthe mount in any desired mannner,. as by an out-turned lip Illa on cupmember I4. Accordingly, movement of the telescope itself bothhorizontally and vertically is resiliently restrained by the device I3-I4.

The body I of the mount is also provided with a lower recess toaccommodate a movable .iaw I9. which cooperates with a stationary jaw 20to. clamp the mount against a suitable fitting on the rifle barreladjacent the rear sight position of the` rifle.

manually operative knob projects into a threaded aperture in the bodyof. the mount.

In accordance with the invention, the structure described is unusuallysimple in construction and precise in its operation. A positive ad-`iusting action is obtained and after the adjust--k ment is made, theparts may be rigidly secured,

in position and not be affected by the ordinary use and manipulation ofthe riiie upon which the mounting device is secured. l
